JOE IVI. LUNZ, 0F WRIGHT, KANSAS.

THRASHER.

Application led October 19, 1921. Serial No. 508,775.

To @ZZ whom t may concern.'

Be it known that I, Jon M. LUNZ, a citizen of the United States, and resident of Vright, in the county of Ford and State of Kansas, have invented certain newand useful Improvements in Thrashers, of which the following is a specification.

This invention relates to thrashers and more particularly to the grain separating means therefor.

An important object is to provide va grain separator for thrashing machines having novel means whereby the same will thoroughly separate the grain from the chaff and the tailings so that the necessity of returning the grain to the cylindrical beater and concave is dispensed with.

A further object of the invention is to provide a thrashing machine having novel means whereby the blast of air through the separator may be regulated for operating under a variety ofconditions.

Other objects and advantages of the invention will be apparent during the course of the following description. y

In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a detail view of a thrashing machine equipped with the improved separator and wind board. I

Figure 9. is a perspective kof the improved separator applied to the shoe of the thrashing machine.

Figure 8 is a perspective of a shoe of a thrashing machine.

Figure 4 is a perspective of a separating member embodied in the invention.

Figijire 5 is a perspective of a wind board' embodied in the invention.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral l5 generally designates a thrashing machincespecially adapted for thrashing grain. such. for instance asbarley, rye, alfalfa or other small grain. The thrasher is of the conventional type and is provided with the. usual cylindrical beater 7 beneath which concave 8 is arranged, the said cylinder' 7 and the concave 8 being adapted to remove the grain for subsequent separation from the chaff, the tailings and the like. Upon being discharged from the concave 8, the grain and the tailings drop onto a grain board 9 and from the `y grain board 9 drop onto the separator generally designated by the numeral -10 and 4,which forms the subject matter of this inin superposed relation and are spaced by depending sides 21, the said depending sides 21 being provided with the lugs 17 which lit into the notches 16'ofy the flanges 14;. It lis thus seen that the endsof the stud 'chatters 18, 19 and 2() mayl be adjustably connected to the inwardly directed shoes 14. The lower V,stub chaifer 2O has its depending` side 21 eX- tended forwardly to provide arms 211 having longitudinal slots 25 kadapted for registration with openings 2G. The arms 2a of -which there are two may be adj ust-ably secured to the sides 12 of the shoe 11 by means of bolts 27 which may bexeXtended through the slots 25 and the proper opening 26. W It isfthus seen that the inclination of thestub chalfers 18, 19 and 2O may be varied to meet the yrequirements of the grain `being thrashed.

- As more pz'xrticularly illustrated in Figure 2 a tailings chatter 8O of elongated formation is mounted upon the shoe in advance of the stub cha'lfers and consistsof a plurality of spaced parallel beams 31 to which spaced parallel quarter .round strips '32 are connected. The short tailings of wheat which do not pass through the stub chalfers arefconducted along the tailing cl'lalfer v31` and are conveyed by the elevator 3,5 tothe cylinder 7 and the concave 8.

The grain upon passing through the stub chali'ers 18, 19 and 2O drops upon a sieve 86 and upon lpassing through the seive is conducted outof the .machine `by means of a conveyor 37. It willbe observed thatV the bolts 27 provide a means whereby the tailings chaffer 3() may be readily and conveniently adjusted. Also the pitch of the same may be varied. In the use of the device the forwardly extending arm 2a may be readily and conveniently adjusted. by means of the bolts 27.

The chaff and the other like matter is introduced into the stacker by means of a sol blower 40 arranged rearwardly of a double wind board generally designated by the numeral 41 and illustrated in detail in Figure 5. As illustrated in Figure 5 the double wind board 4l consists of upper and lower boards 42 connected by end walls 43 and an intermediate guide wall 44.

In operation the wind board 4l may be adjusted to any desired angle by means oit a handle 48 so that the blastot` air fromv the fan or blower 40 may be controlled. The lower board of the wind board is somewhat wider than the upper board and the center board 44 acts as a means to direct the air straight through the wind board in case of a. side draft. Also by this manner of air control the entire surface of the separator is utilized.

By the use of the improved separator all of the grain is separated on its first movement through the thrashing machine and nothing but stems, white caps and small particles which are not blown out through the chatter by the air are returned to the cylinder to be thrashed again. However the grain moves down through the sieve and is carried oitl` by means of the conveyor 37. By reason of this construction the operator may adjust the concave up close to the cylinder thereby insuring theJ removal ot all the grain from the straw.

Having thus described my invention what I claim is zl. In a thrashing` machine, the combination with a shoe having inwardly directed terminal portions of a plurality ol? stub chafi'ers having lngsadj ustably connected to said inwardly directed portions and a tail ing chaiier connected to said shoe.

2. In athrashing machine, the combination with a U-shaped shoe having inwardly directed terminal portions, of a plurality of stub chatters having lugs adjust-ably connected to said inwardly extending portions, and a tailing chatter connected 'to said shoe.

3. In a thrashing machine, the combination with a U-shaped shoe having inwardly directed terminal portions, of a plurality ot stub chatters having lugs adjustably connected to said inwardly extending portions, a tailingl chaer connected to said shoe, and a sieve arranged beneath said stub and tailing chatters.

4. In a thrashing machine, the combination with a U-shaped shoe having inwardly directed terminal portions7 of a plurality of stub chatters having lugs adjustably connected to said inwardly extending portions, a tailing chaHer connected to said shoe, a sieve arranged beneath said stub and tailing chaiiers, and a wind board for directing a blast of air to said stub chatters.

5. In a thrashing machine, the combination with a U-shaped shoe having spaced sides and inwardly directed tlanges provided with notches, a plurality of superposed stub chatters mounted upon said shoe and having depending sides provided with lugs adjustably received within said notches whereby to adjustably connect the stub chatters to the shoe, certain oi? said depending sides being provided with extensions constituting arms, said arms being` provided with slots, and means extending through said slots and spaced sides of said shoe to adjustably connect the arms to said spaced sides.

6. In a thrashing machine, the combination with a U-shaped shoe having spaced sides and inwardly directed flanges provided with notches, a plurality oit siuwrN posed stub chatters mounted upon said shoe, and having depending sides provided with lugs adjnstably received within said notches whereby to adjnstably connect the stub chatters to 'the shoe, certain ot said depende ing sides being provided with extensions constituting arms, said arms being provided with slots, means extending through said slots and spaced sides oi' said shoe to adjustably connect the arms to said spaced sides, and ay tailing chailger connected to said spaced sides.

7. In a thrashing machine, the combination with a U-shaped shoe having spaced sides and inwardly directed flanges provided with notches, a plurality or superposed stnh chatters mounted upon said shoe and havingl depending sides provided with lugs adjustably received within said notches whereby to adjnstably connect the stub chaii'ers to the shoe, certain ot said depending i ing` provided with extensimis cfinstituting arms, said arms being orovided with slots, means extending through said slots` and spaced sides of` said shoe to adjustably connect the arms to said spaced sides, a tailing chatter connected to said spaced sides, and a sieve carried by said shoe beneath said chaders.
